/* ** ** Swift/XRT hardness ratio for 3C 273. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 58134.535878 0.000535 0.39406 0.06665 0.96757 0 1.93519 0.17784 1.39931 0.12799 0.76259 0.10827 0.56498 0.08003 58134.536856 0.000443 0.35849 0.06034 0.98039 0 2.69367 0.23511 1.83175 0.15990 0.96564 0.13897 0.65740 0.09463 58134.537739 0.000440 0.45923 0.08099 0.96053 0 2.12610 0.21119 1.45596 0.14460 0.97638 0.14229 0.66830 0.09735 58134.538555 0.000376 0.54576 0.09814 0.98462 0 2.12280 0.23284 1.43862 0.15777 1.15854 0.16509 0.78604 0.11199 58134.539377 0.000446 0.44109 0.07665 0.96104 0 2.19187 0.21041 1.50517 0.14449 0.96681 0.14004 0.66278 0.09597 58134.540216 0.000394 0.47858 0.08482 0.97794 0 2.19874 0.22204 1.53648 0.15513 1.05227 0.15327 0.73363 0.10687 58134.541159 0.000550 0.32147 0.05256 0.98421 0 2.47010 0.20148 1.68884 0.13772 0.79407 0.11251 0.54081 0.07661 58134.542287 0.000579 0.32233 0.05324 0.96500 0 2.37721 0.19594 1.59429 0.13140 0.76625 0.10966 0.51362 0.07350 58134.543306 0.000440 0.50508 0.08880 0.96053 0 1.99105 0.20574 1.34925 0.13940 1.00565 0.14306 0.68252 0.09709 58134.544197 0.000451 0.44253 0.07657 0.96795 0 2.14810 0.20887 1.48095 0.14397 0.95059 0.13606 0.65648 0.09394 58134.545572 0.000923 0.38841 0.04889 0.96552 0 2.19151 0.14911 1.50997 0.10270 0.85120 0.09015 0.58684 0.06212
